Management of Content-Centric Networking

National audienceInformation-Centric Networks are very promising alternatives to the current Internet architecture. These new network architectures expose multiple positive features heavily studied around the globe today such as in-network caching to save resources, opportunistic routing for easy mobility and authentication of content. However, their management plane and security issues have received much less attention so far. As the Future Internet will be built on these networks, there is an urgent need for a next-generation management framework to manage ICN networks and in fact to constitute their missing management and security plane, which is essential for their success as clean-slate technologies. Indeed, these new networks need to redesign existing solutions for network monitoring, security, configuration, interoperability or accountability. This tutorial aims at surveying the key challenges in management and monitoring of ICN networks. We will more precisely focus on the Content-Centric Networking architecture and describe a recent advance in this field which is a proposal of CCN firewall

Bluetooth Mesh under the Microscope: How much ICN is Inside?

Bluetooth (BT) mesh is a new mode of BT operation for low-energy devices that offers group-based publish-subscribe as a network service with additional caching capabilities. These features resemble concepts of information-centric networking (ICN), and the analogy to ICN has been repeatedly drawn in the BT community. In this paper, we compare BT mesh with ICN both conceptually and in real-world experiments. We contrast both architectures and their design decisions in detail. Experiments are performed on an IoT testbed using NDN/CCNx and BT mesh on constrained RIOT nodes. Our findings indicate significant differences both in concepts and in real-world performance. Supported by new insights, we identify synergies and sketch a design of a BT-ICN that benefits from both worlds

Named Data Networking: a Natural Design for Data Collection in Wireless Sensor Networks

International audienceNamed Data Networking (NDN) is a promising paradigm for the future Internet architecture that also opens new perspectives in the way data can be retrieved in Wireless Sensor Networks (WSNs). In this paper, we explore the potentialities of the NDN paradigm applied to WSNs and propose enhancements to the NDN forwarding strategy by including principles inspired by traditional data-centric routing schemes. Results achieved through the ndnSIM simulator confirm the viability and effectiveness of the proposal

SoK: Distributed Computing in ICN

Information-Centric Networking (ICN), with its data-oriented operation and generally more powerful forwarding layer, provides an attractive platform for distributed computing. This paper provides a systematic overview and categorization of different distributed computing approaches in ICN encompassing fundamental design principles, frameworks and orchestration, protocols, enablers, and applications. We discuss current pain points in legacy distributed computing, attractive ICN features, and how different systems use them. This paper also provides a discussion of potential future work for distributed computing in ICN.Comment: 10 pages, 3 figures, 1 table. Accepted by ACM ICN 202

Content-based publish/subscribe networking and information-centric networking

On-line information comes in different forms and is accessed in different ways and for different purposes. For example, a recording of Beethoven’s Ninth Symphony differs from a storm warning from the local weather service. Beethoven’s Ninth is a large media file with perpetual validity that is typically accessed on demand by users. By contrast, a storm warning is a small ephemeral message typically pushed by the weather service to all users in a specific geographic area. We argue that both should and would be well supported by an information-centric network. More specifically we argue three points. First, modern applications, reflecting the nature of human communications, use and transmit large and long-lived files as well as small ephemeral messages. Second, accessing those two types of information involves significantly different operations within the network. Third, despite their differences, both types of information would benefit from an addressing scheme based on content rather than on more or less flat identifiers, which means that both should be integrated to some extent within a unified contentbased routing infrastructure

Improved Caching Strategies for Publish/Subscribe Internet Networking

MEng thesisThe systemic structure of TCP/IP is outdated; a new scheme for data transportation is needed in order to make the internet more adaptive to modern demands of mobility, information-driven demand, ever-increasing quantity of users and data, and performance requirements. While an information centric networking system addresses these issues, one required component for publish subscribe or content-addressed internet networking systems to work properly is an improved caching system. This allows the publish subscribe internet networking to dynamically route packets to mobile users, as an improvement over pure hierarchical or pure distributed caching systems. To this end, I proposed, implemented, and analyzed the workings of a superdomain caching system. The superdomain caching system is a hybrid of hierarchical and dynamic caching systems designed to continue reaping the benefits of the caching system for mobile users (who may move between neighboring domains in the midst of a network transaction) while minimizing the latency inherent in any distributed caching system to improve upon the content-addressed system

Exploring Computing Continuum in IoT Systems: Sensing, Communicating and Processing at the Network Edge

As Internet of Things (IoT), originally comprising of only a few simple sensing devices, reaches 34 billion units by the end of 2020, they cannot be defined as merely monitoring sensors anymore. IoT capabilities have been improved in recent years as relatively large internal computation and storage capacity are becoming a commodity. In the early days of IoT, processing and storage were typically performed in cloud. New IoT architectures are able to perform complex tasks directly on-device, thus enabling the concept of an extended computational continuum. Real-time critical scenarios e.g. autonomous vehicles sensing, area surveying or disaster rescue and recovery require all the actors involved to be coordinated and collaborate without human interaction to a common goal, sharing data and resources, even in intermittent networks covered areas. This poses new problems in distributed systems, resource management, device orchestration,as well as data processing. This work proposes a new orchestration and communication framework, namely CContinuum, designed to manage resources in heterogeneous IoT architectures across multiple application scenarios. This work focuses on two key sustainability macroscenarios: (a) environmental sensing and awareness, and (b) electric mobility support. In the first case a mechanism to measure air quality over a long period of time for different applications at global scale (3 continents 4 countries) is introduced. The system has been developed in-house from the sensor design to the mist-computing operations performed by the nodes. In the second scenario, a technique to transmit large amounts of fine-time granularity battery data from a moving vehicle to a control center is proposed jointly with the ability of allocating tasks on demand within the computing continuum
